I am very much supporting you! Both code colorizing and AJAX editing preview.
The usability initiative intends to do both, in addition to code folding (compressing long and complicated things such as templates, table calls and references into a small placeholder than can be expanded at wish).
And maybe a links "code completion" - when yuu press [[ it will open an JS-generated dialog with drop-down title search list.
We've done something similar to this idea, and hope to deploy it on Wikipedia soon. Basically it's a toolbar button that launches a link dialog with title suggestions for internal links.
